A fully stereodivergent, dual catalytic α-allylation of linear aldehydes proceeds via direct iridium-catalyzed substitution of racemic allylic alcohols with enamines generated in situ. The use of an Ir(P,olefin) complex and a diarylsilyl prolinol ether as catalysts in the presence of dimethylhydrogen phosphate as the promoter is crucial for achieving high enantio- and diastereoselectivity.
